The header stack-barge was a device that farmers on the American and Canadian plains invented to adapt wheat harvesting machinery to the special requirements of their semi-arid region. Although it appeared at points scattered throughout the length of the North American plains, its greatest use was in Alberta and Saskatchewan during the 1930s. The development of the header stack-barge was an outstanding example of folk technology in the agricultural history of the Great Plains, showing the conditions under which folk invention might flourish and the way it might interact with government extension agents. The case of the header stack-barge then is of consequence both to folklore and to concepts of Great Plains regionalism. 相似文献

Moving and union dissolution 总被引:1,自引:0,他引:1
This paper examines the effect of migration and residential mobility on union dissolution among married and cohabiting couples. Moving is a stressful life event, and a large, multidisciplinary literature has shown that family migration often benefits one partner (usually the man) more than the other Even so, no study to date has examined the possible impact of within-nation geographical mobility on union dissolution. We base our longitudinal analysis on retrospective event-history data from Austria. Our results show that couples who move frequently have a significantly higher risk of union dissolution, and we suggest a variety of mechanisms that may explain this. 相似文献

Two overseas survey-based scales measuring perceived quality of neighbourhood were adapted and replicated in a New Zealand
context. An Italian study (Bonaiuto, Fornara, and Bonnes. (2003). Landscape and Urban Planning, 65, 41–52) measuring Perceived Residential Environmental Quality (PREQ) and an American study (Carp and Carp. (1982). Journal of Environmental Psychology, 2, 295–312) using the Perceived Environmental Quality Indices (PEQI) were applied to a sample of Auckland residents, separated
into low, medium, and high population density areas. The surveys measured attitudes towards subjects such as noise, neighbours,
accessibility, green areas, welfare services, recreational services, safety, maintenance, environmental health, transport
services, and characteristics of an ideal neighbourhood, and were completed by 369 respondents. Primary analyses examined
differences in perception across the three density groups. The factor structures of both scales were replicated with the Auckland
sample, and differences across densities were found for subscales of the PREQ. The results are discussed in relation to the
cross-cultural similarities of perceived environmental quality, and the concept that environmental satisfaction is based on
balancing aspects of the residential environment is proposed.

There are obvious reasons why residential construction should depend on the population’s age structure. We estimate this relation
on Swedish time series data and Organization for Economic Cooperation and Development panel data. Large groups of young adults
are associated with higher rates of residential construction, but there is also a significant negative effect from those above
75. Age effects on residential investment are robust and forecast well out-of-sample in contrast to the corresponding house
price results. This may explain why the debate around house prices and demography has been rather inconclusive. Rapidly aging
populations in the industrialized world makes the future look bleak for the construction industry.

A single latent variable model of health status and therapeutic health care utilization is estimated for parents and own children
of 6,557 US households. The equation system that identifies latent health status simultaneously determines a number of indicators
of general health, including presence of morbidity symptoms, mobility limitations, medication needs, and utilization of therapeutic
health care services. The main goal of the paper was to obtain an unbiased estimate of parents’ marginal substitution rate
between own and child health. Results indicate that parents’ valuation of their children’s health exceeds their valuation
of own health by almost twofold on average.

Right in Amsterdam’s picturesque Canal Zone, on and around Zeedijk, Chinese entrepreneurs have carved out a presence in what seems like the local Chinatown. The businessmen have been targeting Asian and non-Asian customers by offering products that – to an extent – can be associated with Asia, China in particular. Since the early 1990s, individual entrepreneurs and their business organisations have campaigned for official acknowledgement of Zeedijk as an ethnic-only district and for governmental support of the enhancement of Chineseness. Following Hackworth and Rekers. [(2005). “Ethnic Packaging and Gentrification. The Case of Four Neighborhoods in Toronto.” Urban Affairs Review 41 (2): 211–236], we argue that this case challenges traditional understandings of ethnic commercial landscapes. In sharp contrast to the current orthodoxy, which would conceive the proliferation of such an ‘ethnic enclave’ as part of a larger process of assimilation, we have approached Amsterdam’s Chinatown first and foremost as a themed economic space: Chinese and other entrepreneurs compete for a share of the market and in doing also for the right to claim the identity of the area. What is the historical development of the Zeedijk area, how did Chinese entrepreneurs and their associations try to boost Chinatown and negotiate public Chineseness, and how did governmental and non-governmental institutional actors respond to those attempts? 相似文献

The aim of the article is to analyze and to critically examine use of the concept of heteronormativity. We find it important to adjust the concept to some extent in order to analyze, for example, changes occurring in homosexual families, contemporary gender-equal families, or the progressive youth culture. We find two approaches when using the concept. One minimizes the importance of how sexual practices are embedded in social institutions. The first approach becomes too idealistic, whereas the second approach often is based on a structural view of society. This approach makes it hard to imagine a transformation of the family that could lead to more equal and democratic relations in contemporary families. We suggest a third approach, and the possibility of finding creative ways of analyzing actual change and contestations of heteronormativity. An approach containing a space of reflexivity and aiming at political change both involving subjects as well as structures. 相似文献

Following every U.S. decennial census since 1960, the U.S. Census Bureau has evaluated the completeness of coverage using two different methods. Demographic analysis (DA) compares the census counts to a set of independent population estimates to infer coverage differences by age, sex, and race. The survey-based approach (also called dual system estimation or DSE) provides coverage estimates based on matching data from a post-enumeration survey to census records. This paper reviews the fundamentals of the two methodological approaches and then initially examines the results of these two methods for the 2010 decennial census in terms of consistency and inconsistency for age groups. The authors find that the two methods produce relatively consistent results for all age groups, except for young children. Consequently, the paper focuses on the results for children. Results of the 1990, 2000, and 2010 decennial censuses are shown for the overall population in this age group and by demographic detail (age, race, and Hispanic origin). Among children, the DA and DSE results are most inconsistent for the population aged 0–4 and most consistent for ages 10–17. Results also show that DA and DSE are more consistent for Black than non-Black populations. The authors discuss possible explanations for the differences in the two methods for young children and conclude that the DSE approach may underestimate the net undercount of young children due to correlation bias. 相似文献
